Abstract: A shoe insert is configured as a single component with a specifically-configured shape that provides internal shoe structural support while enhancing airflow within the shoe. The shoe insert is comprised of a rigid structure, such as plastic, that engages with the inner and outer sides of the shoe to provide sufficient support. The shoe insert's inner and outer sides, which engage with the shoe's inner and outer sides, have a grip portion with an upper opening substantially positioned at the shoe's ankle opening. This upper opening enables air to flow therethrough and provide breath to the shoe's interior cavity. Airflow holes spread sporadically throughout the shoe insert's body enables air to flow through the shoe insert and engage the shoe to provide breathability, thereby preventing moisture, mold, and stench.

Abstract: Systems and methods are described herein for improved operation and troubleshooting of a printing device. A printing device includes a master module wherein printing device operation data can be stored in non-volatile memory. The master module is provided with non-volatile memory or an uninterruptible power source so that the master module memory may be retained and dumped upon request. The memory dump may transmit the memory contents to a local external device through a port, such as an infrared port or a USB (Universal Serial Bus) port, or the memory contents may be transmitted to a remote location. The dumped data may then be analyzed to quickly identify a problem component in the printing device.

Abstract: A tester print head has at least one conductive pad that is coupled to a status return pad by circuitry. The tester print head is inserted into a printer carriage assembly that is linked to printer control circuitry through linking hardware. A self-test signal is applied to the linking hardware. If the tester print head provides an indication to the control circuitry that the self-test signal was received, the linking hardware passed the self-test. If the indication is not provided to the control circuitry, the self-test failed and the functional print head that was replaced by the tester print head may be operating properly.
